Red Bull plans KERS upgrade for Turkey

Both Sebastian Vettel and Mark Webber have encountered problems with their KERS at every race held so far this season - with the issues almost certainly playing a part in preventing Vettel extending his winning streak in China last weekend.

And although the team still has a number of issues to overcome before it can be confident it has got on top of the KERS problems, team principal Christian Horner says that he is optimistic about the work being done.

"We have got another upgrade of KERS coming for Turkey," he explained. "It is getting better and better as we get more understanding of the system and more mileage on it.

"So I am confident that the niggly issues that we have with it, we have fixes in the pipeline."

Red Bull Racing's KERS problems are believed to be related to cooling issues of its in-house battery system - which has been packaged extremely tightly so as not to compromise the car's aerodynamics.

The team is also not as experienced in the running of KERS as other outfits, having not raced the device in 2009 and only fitting it to this year's car for the latter stages of winter testing.

Webber said after the race in China that it was important the team got a grip on the KERS issues as soon as possible.

"It's a key component in Formula 1 these days, mate, so it's completely obvious that we want to address it as soon as possible," he said. "McLaren have a huge amount of experience with Mercedes from 2009 and they're doing a good job of it, and that's not an excuse, it means that we have to work harder, we have to work as cleverly as we can and as fast as we can.

"Fortunately, we now have a bit of a break, so it will be a clear focus for us in terms of durability and consistency and also understanding the system. It's not only a performance thing but it's also incredibly disrupting in the garage for... my car was rebuilt about four times this weekend. It makes it so much harder for them in terms of making mistakes, when you open a car up and put it back together all the time, it's not easy.

"We have awesome guys on the case. As I say, with the limited experience we have, that's the way it is and we're still going okay in the Constructors' Championship, I think, so let's regroup, get to Turkey and work hard on it."
